ROBERT T. JOHNSTON, OF PLAINFIELD, NEW JERSEY, ASSIGNOR, BY

MESNE ASSIGNMENTS, TO DETROIT TRUST CO., TRUSTEE, OFv DE- TROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

PRINTING-PRESS.

Application filed January 13, 1899.

To @ZZ whom i may concern.-

Be it known that I, ROBERT T. JOHNSTON, a citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented a new and useful Improvement in Printing Presses, of which the following is a specification.

The aim of this invention is to improve web-printing machines, and especially relates to improvements in the web-associating mechanism used therewith.

The improvements have been especially designed for use in connection with a traveling-cylinder web-printing machine, although the same are capable of general application.

Referring to the two sheets of drawings, forming part of this application, I will describe my improvements in detail.

In said drawings, Figure 1 is a rear elevation of one form of traveling-cylinder webprinting machine with my improvements applied thereto. Fig. 2 is a plan view of the improved web-associating mechanism, and Fig. 3 is an end elevation of the parallel rolls used in connection therewith.

Referring to the drawings and in detail, 20 designates the side frames of the machine, between whichV are arranged form-beds A and B.

O designates the cylinder-carriers in which are journaled the impression-cylinders 31 and 38. Suitable form-inking rollers and distributing-rollers are arranged in the carriers at each side of each impression-cylinder to take ink from the ink-fountains E and deposit the same upon the forms. The web w is drawn from the web-roll W and is led around guides 22 and 23 to the feeding-in drum 24. Coacting with the drum 24 is a set of tapes 25, which passes around suitable tape-pulleys 26, 27, and 28. The web then passes to a roller or guide 29, mounted in the carriers, up around a looping rollerl 30, down around the first impression-cylinder 31, up around another looping-roller 32, then around a guide 33, also carried by the carriers. The web then passes around guides 34 and 35 at the end of the machine. The web is then led to a guide 36, up around a looping-roller 37, down Aaround the second impression-cylinder 38, up around another looping-roller 39, then around a guide 40, the parts 36 to 40 being also mounted in the carriers. From the roll 40 the web is led to a Speccation of Letters Patent.

guide 41, then to a continuously-running feeding-out drum 42, coacting withwhich is a set of tapes 43, which turn around tape.-y pulleys 44, 45, and 46. From the feedingout drum 42 the web is manipulated, as here.- inafter described.

The driving mechanism is arranged as follows: represents the driving-shaft, to which power isv applied by any suitable means. On this shaft is arranged a bevelinion 51, which engages and drives avlarge evel-gear 52, which is mounted on the end of a vertical shaft 53, which carries a crank-pinl which engages a yoke connecting the carriers, so that the cylinders will be reciprocated. Also mounted on the shaft 50 is` a pinion 56, which meshes with an intermediate 57, which intermediate drives a geary 1 58, arranged on the shaft 59 of the feeding-in drum 24. Also engaging the pinion 56 is an intermediate gear 60, which drives. al camshaft 61, which is geared to make` two turns for each reciprocation ofthe cylinders. The cam-shaft 61 carries a screw-cam 62.

63 designates a longitudinal shaft extend#` ing parallel vto the movement of the carriers, which is journaled in bracketsl 64 and 65, secured to the frame 20. On the end of the shaft 63 is secured an arm 66, which has a roller 67, engaging the cam 62. Extending from the rear carrier C are brackets 68 and 69, between which is i'itted a bush or sleeve 70, which is keyed on said shaft 63. EX- tending from the bush 70 is an arm 71, which connects by links 72 to an arm 73, mounted on shaft 74, journaled in the carriers, which shaft has walking-beam arms 75, in which the looping-rollers 30 and 32. are

journaled. Also extending from the bush 7 is an arm 76, which connects by link 7.7 to anarm 78, fitted on shaft 79, journaled in-the carriers, which shaft carries walking-beam arms 80, in which the looping-rollers 37. and 39 are journaled.

The press before described is substantially that shown and described in an application for patent filed of even date herewith by Henry A. Wise Wood, Serial No. 702,104.

The Operation is such that the web will be printed on both the forwardy and backward movements of the impression-cylinders, and the web in the press will run continuously., except the small sections which lie directlyV around the peripheries of the two impression? IOO cylinders, and these small sections will be shifted forward when the cylinders reverse off the forms at either end of the beds. I have shown this form of machine as one to which my improvements are' especially applicable.

My first improvement consists in the form of driving-gearing. y.

The web after being printed, as before described, passes to the continuously-running feeding-out drum 42. The feeding-out drum has three grooves 200, 201, and 202.

203 designates a slitter which may be adjusted to coperate with either groove 201 or 202'to slit the web into two sections. The

,groove 200 is arranged at the center line of a longitudinal folder 122, and the right-hand section of the web in Fig. 2 can be led directly to said longitudinal folder by means of rolls 121 and 123. The roll 121 preferably has a groove in line with the groove 200, so that the central pasted line can be properly carried to the former. Arranged between said frames is a large shaft or pipe 119, adjustably secured on which is a bracket 120. Arranged between a bracket 125, extending in from the side frame 21, and said bracket 120 are two turners 204 and 205, arranged in substantially the same horizontal plane. Also arranged between said bracket 1 20 and the side frame 20 is a turner 206. Arranged in brackets projecting in from the side frame 20 are four parallel rolls 207, 208, 209, and 210. By this arrangement four, six, or eight page papers or multiples thereof can be roduced of different widths-as, for examp e, six or seven columns wide-without the adjustment of any of the turners, parallel rolls, or folder.

The following is the way this device is used, and in the following description the margins on the web outside the printed matter are neglected. lf a four-page six-column paper is wanted, a web 211 of a width equal to two six-column pages is run through the machine, so as to come to the roller 42 with its center in line with the center of the lon gitudinal folder, and the same is carried directly to the longitudinal folder by means of rolls 121 and 123. Tf a four-page paper seven columns wide is desired, a web 213 of a width equal to two pages of seven columns i` Y wide is similarlyrun through the machine.

If an eight-page six-column paper is wanted, a web of a width equal to four pages of six columns wide is run through the machine and is slit on the groove 201 into two webs 211 and 212. The web 211 is'passed directly to the former. The web 212 is deflected up over the turner 205, up around the rolls 207 and 208, and up over the turner 206 to come on top of t-he web 211. If an eight-page seven-column paper is wanted, a

web of a width equal to four pages of seven columns is run and the same is slit on the groove 202 into two webs 213 and 214. The

web 213 is passed directly to the former, and the web 214 is led up over the turner 204, up over the parallel' rolls 209 and 210, and then up over the turner 206. If a six-page paper of six columns is desired, a web of width equal to three six-column pages is run through the machine and is slit on the groove 201 into two sections 212 and 215. The section 2 15 is passed directly to the former, and the section 212 is deflected around the turner 205, parallel rolls 207 and 208, and turner 206 to come on top thereof. lf a six-page paper of seven columns width is desired, a web of a width equal to three pages of seven columns each is run, and the same is slit on the groove 202 into two sections 214 and 216. The section 216 is passed directly to the former, and the section 214 is deflected up over turner 204, parallel rolls 207 and 208, and turner 206 to come on top thereof.

The various turners and parallel rolls before referred to are accurately set when the machine is erected and need not thereafter be adjusted. The various rolls are so set that the sections of the web will register longitudinally and transversely without adjustment of the forms. Thus it will be seen that the machine is ready to produce without adjustment, except of the slitter, any of the great variety of products before mentioned, and that the adjustment of the turners, &c., is dispensed with. This enables the pressman to very quickly thread the machine up for the proper paper desired. 4

The figures before given are merely illustrative and other relative-sized papersmay be produced without departing from the scope of my invention.

This web-associating mechanism, although especially useful in the style of machines indicated is also capable of general application.

Having thus fully described the details of my invention and the best method known to me for putting the same into practice, what T claim, and desire to secure by Letters Patent, is

1. The combination in a web-associating mechanism of an adjustable slitting mechanism, a longitudinal former, three turnerbars, and web-directing rolls arranged so that the plicated product can be made of different widths.

2. The combination .in a web -associating mechanism of two parallel turner-bars, and another turner-bar arranged so that two sections of web can be associated together and the plicated product made either one of two 1widths and registered on the same center ine.

3. The combination in a web-associating mechanism of a web-forwarding roll, two grooves therein, a slitter which may be set to cooperate with either groove, two turnerbars, a third turner-bar, and a longitudinal former, the whole so arranged that a wide IOO IOS

web can be slit into two sections and the sections associated and advanced to the longitudinal former with the central line of the plicat'ed product coinciding with the apex or nose of the former, and said plicated sections made either one of two widths.

4. The combination in a web-associating mechanism of web-forwarding roll 42, having grooves 200, 201, 202, adjustable slitter 203, turner-bars 204 and 205, a third turner-bar, and a longitudinal former having its apex arranged in the same vertical plane as groove 200.

5. The combination in a web-associating mechanism of a device for slitting a web into two sections, a longitudinal former, guidingrolls for directing one of said sections directly to the former, an adjustable slitting mechanism, two turner-bars, and a third turner-bar, the whole arranged so that a double section of web may be formed from a wide web and led to the longitudinal former with its central line registering with the apex thereof and said double section made either one of two ways.

6. The combination of turners 204 and 205,

suitable parallel rolls and turner 206 arranged so that two sections of web can be associated and said sectionsmade of either one of two widths.

7. The combination of turners 204 and 205,

parallel rolls 207 and 208, 209 and 210, and turner 206.

8. The combination of' a slitting mechanism, whereby a wide web can be slit into two sections, said slitting mechanism being adjustable so that diiierent widths of web can be used, turners 204 and 205, suitable parallel rolls and turner 206.

9. The combination of roll 42 having slitting-grooves 201 and 202, a suitable adjustable slitter cooperating therewith, turners 204 and 205, parallel rolls 207 and 208, and 209 and 210, and turner 206.

10. The combination of a web-forwarding roll as 42, suitable adjustable slitting mechanism, web-guides arranged so that one section of web can be led directly to a longitudinal folder, turners 204 and 205, suitable parallel rolls and turner 206 arranged so that different width sections of web can be associated and brought to register both transverselyT and longitudinally without adjustment of any of the turners or parallel rolls.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
